1. DESCRIPTION When troubleshooting OBD II (On-Board Diagnostics) vehicles, the Techstream (complying with SAE J1987) must be connected to the DLC3 (Data Link Connector 3) of the vehicle. Various data in the vehicle's ECM (Engine Control Module) can be then read. OBD II regulations require that the vehicle's on-board computer illuminates the MIL (Malfunction Indicator Lamp) on the instrument panel when the computer detects a malfunction in: The emission control system and components. The powertrain control components (which affect vehicle emissions). The computer itself. In addition, the applicable DTCs prescribed by SAE J2012 are stored in the ECM memory. If the malfunction does not recur in 3 consecutive trips, the MIL turns off automatically but the DTCs remain stored in the ECM memory. To check the DTCs, connect the Techstream to the DLC3. The Techstream displays output DTCs, freeze frame data, and a variety of engine data. The DTCs and freeze frame data can be cleared with the Techstream. In order to enhance OBD function on vehicles and develop the Off-Board diagnosis system, Controller Area Network (CAN) communication is used in this system. CAN is a network which uses a pair of data transmission lines spanning multiple computers and sensors. It allows for high speed communications between the systems and simplification of the wire harness connections.
2. NORMAL MODE AND CHECK MODE The diagnosis system operates in normal mode during normal vehicle use. In normal mode, 2 trip detection logic is used to ensure accurate detection of malfunctions. Check mode is also available as an option for technicians. In check mode, 1 trip detection logic is used for duplicating malfunction symptoms and increasing the system's ability to detect malfunctions, including intermittent problems (Techstream only).
3. 2 TRIP DETECTION LOGIC When a malfunction is first detected, the malfunction is temporarily stored in the ECM memory (1st trip). If the same malfunction is detected during the next subsequent drive cycle, the MIL is illuminated (2nd trip).
4. DLC3 (Data Link Connector 3) Check the DLC3. Refer to «GENERAL INFORMATION»(ref-493943-S32566569402012081000000).
5. FREEZE FRAME DATA The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data stored at the time of a malfunction.
6. BATTERY VOLTAGE Standard voltage 11 to 14 V If voltage is below 11 V, replace or recharge the battery.
7. MIL (Malfunction Indicator Lamp) The MIL is illuminated when the ignition switch is first turned to ON (the engine is not running). The MIL turns off when the engine is started. If the MIL remains illuminated, the diagnosis system has detected a malfunction or abnormality in the system. HINT: If the MIL is not illuminated when the ignition switch is first turned to ON, check the MIL circuit. Refer to «MIL Circuit»(ref-494125-S23000119302012081000000).
8. ALL READINESS HINT: With "All Readiness", you can check whether or not the DTC judgment has been completed by using the Techstream. You should check "All Readiness" after simulating malfunction symptoms or for validation after finishing repairs. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Clear the DTCs. Refer to «DTC CHECK / CLEAR»(ref-493953-S27327777792012081000000). Turn the ignition switch off and wait for at least 30 seconds. Turn the ignition switch to ON and turn the Techstream on. Perform the DTC judgment driving pattern to run the DTC judgment. Enter the following menus: Powertrain / Engine / Utility / All Readiness. Input the DTCs to be confirmed. Check the DTC judgment result. Techstream Display Description NORMAL DTC judgment completed System normal ABNORMAL DTC judgment completed System abnormal INCOMPLETE DTC judgment not completed Perform the driving pattern after confirming DTC enabling conditions N/A Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

DTC CHECK / CLEAR

Note. When the diagnosis system is changed from normal mode to check mode or vice versa, all DTCs and freeze frame data recorded in normal mode are cleared. Before changing modes, always check and make a note of DTCs and freeze frame data.

HINT

1. DTCs which are stored in the ECM can be displayed on the Techstream. The Techstream can display the current, pending and permanent DTCs.
2. If a malfunction is detected during the current driving cycle, current and permanent DTCs are stored.
3. Some DTCs are not stored if the ECM does not detect the same malfunction again during a second consecutive driving cycle. However, such malfunctions, detected on only one occasion, are stored as pending DTCs.
4. Current and pending DTCs can be cleared by using the Techstream or by disconnecting the cable from the negative (-) battery terminal. However, permanent DTCs cannot be cleared using either of these two methods.
5. After clearing current DTCs using the Techstream (or by disconnecting the cable from the negative battery terminal), permanent DTCs can be cleared when the system is determined to be normal for the relevant DTCs and then the universal trip is performed. The driving pattern to obtain a normal judgment is described under the "Confirmation Driving Pattern" for the respective DTC.

2 TRIP DETECTION EXAMPLES

Scheme 20

Scheme 21

HINT

1. Obtaining a normal judgment and performing a universal trip driving pattern can be done in the same driving cycle or in different driving cycles.
2. It is unnecessary to obtain a normal judgment if the DTCs are misfire or fuel system DTCs.

Scheme 22

1. CHECK DTC Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Check the DTC(s) and freeze frame data, and then write them down. Check the details of the DTC(s). Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-493953-S38664206892012081000000).
2. CLEAR DTC (Pending and Current DTC) Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Clear the DTCs.
3. CLEAR DTC (Pending and Current DTC without using Techstream) Perform either of the following operations: NOTE: After turning ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work. Refer to «PRECAUTION»(ref-493943-S27942734662012081000000). Disconnect the cable from the negative (-) battery terminal for more than 1 minute. Remove the EFI NO. 1 and ETCS fuses from the engine room relay block located inside the engine compartment for more than 1 minute.
4. CLEAR PERMANENT DTC HINT: Even if the following procedure is not performed, permanent DTCs are cleared by obtaining a normal judgment during 3 consecutive driving cycles. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Trouble Codes. Check if permanent DTCs are stored. HINT: If permanent DTCs are not output, it is not necessary to continue this procedure. Clear the DTCs. Perform the respective confirmation driving patterns in order to obtain a normal judgment for the output DTCs. HINT: Confirmation driving patterns do not need to be performed for misfire and fuel system DTCs. For the confirmation driving pattern, refer to the procedures for the relevant DTC. Refer to «DIAGNOSTIC TROUBLE CODE CHART»(ref-493953-S38664206892012081000000). Perform the universal trip. HINT: The driving pattern to obtain a normal judgment and the universal trip driving can be performed consecutively in the same driving cycle. Idle the engine for 30 seconds or more. Drive the vehicle at 40 km/h (25 mph) or more for a total of 5 minutes or more. WARNING: When performing the confirmation driving pattern, obey all speed limits and traffic laws. HINT: It is possible to complete the drive pattern even if the vehicle decelerates to less than 40 km/h (25 mph) during the driving cycle provided that the vehicle is driven at 40 km/h (25 mph) or more for a total of 5 minutes. Allow 10 minutes or more to elapse from the time the engine is started. Enter the following menus: Powertrain / Engine / Trouble Codes. Check that the permanent DTCs have been cleared. HINT: The permanent DTCs are cleared when the universal trip is completed.

1. DESCRIPTION The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction. HINT: If it is impossible to duplicate the problem even though a DTC is output, check the freeze frame data. The ECM records engine conditions in the form of freeze frame data every 0.5 seconds. Using the Techstream, 5 separate sets of freeze frame data can be checked. 3 data sets from before the DTC was stored 1 data set from when the DTC was stored 1 data set from after the DTC was stored These data sets can be used to simulate the condition of the vehicle from around the time of the occurrence of the malfunction. The data may assist in identifying the cause of the malfunction, and in judging whether it was temporary or not.

DATA LIST / ACTIVE TEST

1. DATA LIST HINT: Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time. NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Data List / All Data. According to the display on the Techstream, read the Data List.

NOTE: *1: If the display of the Data List item Catalyst OT MF F/C item is Not Avl, perform this Active Test with the vehicle stopped and the engine idling. If the display of the Data List item Catalyst OT MF F/C item is Avail, perform this Active Test as described below. Stop the engine, turn the ignition switch to ON. Enter the Control the Select Cylinder Fuel Cut. Select the cylinder for fuel cut (cylinder #1 to #4) and turn the Active Test ON (press the RIGHT or LEFT button). Start the engine. HINT: *2: In this Active Test, the fuel and ignition of all cylinders is cut. The engine must then be cranked for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders. Warm up the engine. Turn the ignition switch off. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Active Test / Check the Cylinder Compression. HINT: To display the entire Data List, press the pull down menu button next to Primary. Then select Compression. Push the snapshot button to turn the snapshot function on. HINT: Using the snapshot function, data can be recorded during the Active Test While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON. HINT: After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode. Crank the engine for about 10 seconds. HINT: Continue to crank the engine until the values change from the default value (51199 RPM). Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the Techstream. HINT: At first, the Techstream displays extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, each cylinder engine speed measurement will change to the actual engine speed. NOTE: Do not crank the engine continuously for 20 seconds or more. If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine. Use a fully-charged battery. Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops. NOTE: If the Active Test is changed to OFF while the engine is being cranked, the engine will start. Push the snapshot button to turn the snapshot function off. Select "Stored Data" on the Techstream screen, select the recorded data and display the data as a graph. HINT: If the data is not displayed as a graph, the change of the values cannot be observed. Check the change in engine speed values. HINT: As the data values of the Active Test return to their default values when cranking is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during cranking.
3. SYSTEM CHECK (Only for Techstream) HINT: Performing a System Check in the Utility menu enables the system, which consists of multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are stored, and can detect potential malfunctions in the system. Connect the Techstream to the DLC3. Turn the ignition switch to ON. Turn the Techstream on. Enter the following menus: Powertrain / Engine / Utility / Evaporative System Check. Perform the System Check by referring to the table below.
